Here's my entry into the possible standard dice replacement. Not fully thought out on odds, just a spitball/idea.

**Need:** 15d6; 3 dice of one color (the Chance Roll). 6 positive dice of a different color (preferably light). 6 negative dice of yet another color (preferably dark). (yes, 3 different colors of D6's)

Determine base difficulty. This sets the number of positive or negative dice initially added to the pool. (from adding 1 - 3 negative or positive dice)

- Add a positive die to the "pool" for any bonus.
- Add a negative die to the "pool" for any penalties.

Roll all dice together in a pool.

**Chance Roll:**
Set aside chance roll and note result (add 3d6 together).

Attribute Bonus and Skill Ranks add/subtract from "chance" roll. These are the only numbers that impact the actual result of the chance roll.

First, cancel each positive die with a negative die. You will be left with either one or more of one die type. If one or more positive dice are left over, add the result to the chance roll. If one or more negative dice are left over, subtract the result from the chance roll.

TN is always 13 (at or above).

- The higher you roll over 13, the better the success.
- The lower you roll below 13, the worse the failure.

**Advantage or Threat:**
- Rolling doubles on chance roll that matches a negative die = Threat for each negative die that matches.
- Rolling doubles on chance roll that matches a positive die = Advantage for each positive die that matches.

Threat cancels out Advantage (or vice versa) so you end up with only Threat or Advantage. These impact the situation separately from the success/failure of the chance roll. Spend A/T on bonus/penalty dice going forward or buy "special effects".

**Despair and/or Triumph:**
- Rolling triples on chance roll that matches a negative die = Despair
- Rolling triples on chance roll that matches a positive die = Triumph

These impact the situation separately from the success/failure of the chance roll. Despair and Triumph do not cancel each other out. The results should be determined by current circumstances or spent on "special events". You can have both Triumph and Despair in the same roll.
